Abstract
The utility model discloses a generator rotor, which belongs to the field of automobile parts and solves a problem a generator rotor is easily caused to have big vibrate and loud noises because the amount of dynamic balance of a generator rotor in the prior art is relatively high. The generator rotor mainly comprises a rotating shaft, a pair of claw poles, an exciting winding, a front fan blade, a rear fan blade, an inner retaining ring and a sliding ring, wherein the exciting winding is fixed between the two claw poles, both ends of the exciting winding are connected with the sliding ring, the rotating shaft penetrates the two claw poles, the front fan blade, the rear fan blade, the inner retaining ring and the sliding ring, the rotating shaft is provided with a spline A and a spline B, and the rotating shaft is in interference fit with the two claw poles through the spline A and the spline B. The generator rotor disclosed by the utility model is mainly used in automobile generators.
Description
Technical field
The utility model belongs to the auto parts machinery field, specifically, relates in particular to the generator amature that uses on a kind of automobile.
Background technology
Form by rotating shaft, two the pawl utmost points, excitation winding, front and back fan blade and slip rings etc. by the claw-pole generator amature.In the cavity of two pawl utmost points, put excitation winding, and be fitted in the rotating shaft, excitation winding is formed by the high strength enamelled wire coiling, and slip ring is made up of two copper rings insulated from each other, generally adopts the phenolic fibre plastics to be pressed into one, then it is pressed onto in the rotating shaft.Two lead-out wires of excitation winding are welded in respectively on the copper ring that insulate with rotating shaft.The outer round surface of slip ring should be smooth smooth, so that can sliding contact during the rotor high-speed operation and between the brush, when two brushes energisings; The axial magnetic flux that exciting current produces; Make a pawl utmost point be geomagnetic into the N utmost point, another piece is geomagnetic into the S utmost point, thereby has formed N, the S magnetic pole that crosses one another.Generator for electricity generation is because rotor selects dress in stator, does the motion of cutting magnetic line, thereby produces induced potential, draws through binding post, is connected in the loop, has just produced electric current.The computing ballance correction of conventional electric generators rotor causes generator amature vibration and noise big than higher easily.
The utility model content
For the computing ballance correction that solves generator amature in the prior art than higher, cause generator amature vibration and the big problem of noise easily, the utility model provides a kind of new type electric generator rotor.
The utility model is to adopt following technical scheme to realize:
A kind of generator amature; Comprise rotating shaft, a pair of pawl utmost point, excitation winding, preceding fan blade, back fan blade, inner shield ring and slip ring; Said excitation winding is fixed between the said two pawl utmost points and said excitation winding two ends are connected with said slip ring; Said rotating shaft runs through the said two pawl utmost points, preceding fan blade, back fan blade, inner shield ring and slip ring, and said rotating shaft is provided with spline A and spline B, and rotating shaft is through spline A and spline B and two pawl utmost point interference fit.
The length of spline A and spline B be respectively the pawl utmost point thickness 1/2; The magnitude of interference of spline A and spline B is respectively 0.1 millimeter.
Compared with prior art, the utlity model has following advantage and progress: all within acceptability limit, performance is more stable for the rotor dynamic balancing amount after the improvement, also reduces the vibration and the noise of rotor, thereby raises the efficiency.
